Tóm tắt
Chi tiết

Defines classes of microclimatic conditions, to which components (basic parts, assemblies, built-in units) may be subjected inside products, which are used under the climatic conditions as classified in sections IEC 721-3-3 and IEC 721-3-4. Characteristic parameters for the microclimates are high air temperature and high relative air humidity. Further parameters of the climatic classes have not been considered. A limited number of microclimatic classes is specified taking into consideration typical limiting high air temperatures of components.
